SPECIFICATION forming part of Letters Patent No. 789,602, dated May 9, 1905.

Application filed February 8,1904. Serial No. 192.609-

To all whom, it may concern/.-

Be it known that I, (iuo'ae n W. Fos'run, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in \Vinding-b [achines, of which the following is a specification.

My invention relates to machines for winding two or more strands of yarn or thread on a cop-tube, known as doublingf and it consists in providing means whereby the copspindle is carried from the driving-roll and its momentum arrested on the breaking of a thread or strand and means for preventing vibration, shocks, and irregular action and in certain details of construction fully set forth hereinafter and illustrated in the accompanying drawings, in which- Figurel is aside elevation of part of a winding-machine suflicient to illustrate my invention; Fig. 2, a transverse sectional elevation showing in detail the parts at one side of the machine. Fig. 3 is a partial plan showing the package-support and adjuncts; Fig. 4:, a detached view showing the position of parts when the rack-bar is lifted; Fig. 5, an enlarged side elevation of the tension device; Fig. 6, a front elevation; Fig. 7, a plan thereof.

The frame A of the machine is of any suitable construction and has the bearings of the driving-shaft B and for two driving roll-shafts or two sets of roll-shafts 10 10 in line with each other and projecting from opposite sides of the frame, so that the Winding devices are duplicated. Those on one side only are shown. A belt 14 passes around a pulley 12, secured to the shaft B, over a pulley 15 on one of the shafts 10, down and around an idler-pulley 13, turning on the shaft B, and over the pulley 15 of the other roll-shaft 10, and thence back to the pulley 12, the same belt thereby drivingboth the oppositely-arranged shafts 1O 10.

In a longitudinal groove of a guide-bar 8 of the frame, parallel with each shaft 10, reciprocates a carrier 7, supporting the threadguide D, which extends over the roll 16 in position to deliver the thread between the roll and the tube upon the cop-spindle E, driven by the roll, as usual. Each thread-guide D is rcciprocated from a rock-shaft, there being two parallel rock-shafts C C, rocking in bearings on the frame at right angles to the copspindles, and each with an arm 5, connected by a connecting rod or link (i with one of the carriers 7 The rock-shafts are driven by the movement set forth in my Letters Patent No. 766,878, dated August 9, 1904-, fora mechanical movement-that is, each rock-shaft is driven from a crank-disk G through the medium of a connecting-rod 3, one of the disks being wider than the other and driven from a gear 1 on the shaft B, and the other disk from the first, so that the disks turn in reverse directions, the gear 1 being back of that disk which it does not engage. The wrist-pins connecting the rods 3 with the disks are so carried or adjusted that they will not both be at their highest point at the same time, so that the thread-guides at one side of the machine will not reach the limit of their traverse at the same moment as those on the other side of the machine, thereby avoiding that racking of the machine and the resistance to the movements which comes from bringing all the moving parts to the limits of their movements at the same instant. As a result the movements are more regular, less interfered with, and the machine may be driven at a greater speed; further, by the arrangement described is secured the influence of both the disks Gr, acting as balance-wheels, to counter act the momentum of the guides when operating only at one side of the machine at a time and insures a steadier and more regular operation.

In the construction shown the connectingrod 3 is jointed to a wrist-pin 190 on a link 18, oscillating on a pin 2, carried by the disk or wheel G, and has a slot receiving a crank-pin 23 upon a shaft 24:, turning in a reverse direction from the disk; butl do not here describe the details and effect of this arrangement, as the same are fully set forth in a separate application, Serial No. 168,477, and as this connection of the rods with the driving disk or wheel is not a necessary feature of the present invention.

There is a tension device H for each strand or yarn, and from said device the yarn passes over a slotted plate 29, through which extend the bent ends of drop-wires 21, which bear upon the yarns and are supported thereby until on the breaking of a yarn the wire will drop, swinging on its pivot 22 and lifting the upper end of said wire extending beneath a rod 60, the lifting of which by the dropping of any one of the wires actuates the means for raising the cop or package being wound from the driving-drum and arresting its rotation to permit the operator to tie the loose end of the broken strand before the same can be carried to and wound upon the package. Different means may be employed for securing this result upon the breaking of a strand. In the construction shown the cop-spindle E is supported by a box 25, bolted firmly to a lug 25, extending into and held securely by an arm or carrier 28, which swings on aiixed stud 29, supported by a bracket 70. The box 25 is recessed to receive a collar 52 on the spindle E. An arm 30, extending downward from said stud, Fig. l, carries a pivoted block 31, slotted to receive a rackbar 32, which passes through the block, but can be moved vertically in the slot, and which extends across the face of a disk 34: and the teeth at the lower edge of which engage teeth at the bottom of the slot of the block 31. The rack-bar 32 is secured by a pivot-pin 33 to the side of the disk 34, which is upon a shaft 410, turning in bearings of the frame, and which supports a spring 41, one end connected to a collar 94 on the shaft, the other end to the frame, and tending to turn the shaft and disk in the direction of the arrow, Fig. 1. Normally the pivotpin 33 is maintained in the position shown in Fig. 1 by a suitable detent for instance, by the contact of a tooth 39 on the disk 3st with a tooth i2 on a lever i3, which swings on a pin 100 and to which is pivoted a bar i4, carrying the rod 60. On the upper side of the bar 14: is a rounded lug 45, and on a collar on the spindle 10 are symmetrically-disposed rounded projections 46. When the rod is lifted on the breaking of a strand, the lug 45 is brought into position to be struck by a projection L6, and the bar 4A and lever 43 are swung to the right, Fig. l, to carry the tooth 42 from beneath the tooth 39, when the spring 41 will turn the disk 3 1 in the direction of it's arrow to carry down the pivot-pin 33 and draw the rack-bar in the direction of its arrow.

To at once arrest the movement of the cop without shock, I make use of a suitable brake. As shown, the brake is a shoe 50 at the end of an arm 90, connected with the arm 30, and the arm 90 as it is carried upward on the breaking of a strand carries the shoe 50 against a collar 52 on the cop-spindle, bringing the weight of the spindle and cop upon the shoe and lifting the cop from the roll, and thereby causing the quick arrest of the rotation of the cop, but without shock, so that the operator can secure the end of the broken strand-before it is wound on the cop.

It will be noted that the pivotal point 91 of the block 31, the pivot-pin 33,. and the axis of the shaft 4C0 are in substantially the same horizontal plane when the parts are at rest prior to the breaking of a strand and that consequently the movement of the pivot 33 in starting is like that of a wrist-pin on a dead-center and the rack-bar is only started gradually and without any abrupt shock, and if the rackteeth are not fully in mesh with those of the block they are not brought into contact so suddenly as to cause any violent action. To permit any desired change of action, the pivotpin 33 is adjustable in a radial slot 92 of the disk 3 1 in any usual way.

hen the ends have been pieced, the operator can bring the parts back to normal position by rocking the shaft 40 by means of a hand-lever 61, which carries the tooth 39 past the tooth t2, after which the'lever 43 will under the influence of spring 43 assume a vertical position, carrying the rod 60 to the position shown in Fig. 1, and this also forces a pin 97 on the disk 34 against the inner end of the rack-bar, lifting the outer end of the rack-bar upward in the slot of the block 31 and disengaging the teeth of the rack and block, when the weight of the package will bring it back in position upon the drum, the slot in the block 31 guiding the end of the rack-bar in its slightly-upward movement. As the package increases in diameter the block will slide gradually toward the shaft 40, the bevel of the engaging teeth permitting the block to be carried in this direction. The extent of the downward motion of the shoe 50 and connections is determined by a set-screw 54, Fig. 1, the shoe being out of contact with the collar 52 when the package rests on the roll and the arm 90 being lifted by contact with the screw as the cop increases in diameter.

It is well known that in machines of the class described where the cop is driven by surface contact with a driving drum or roll considerable vibration is caused by the uneven surface of the paper tube or holder or when there are any irregularities in the cop, and to prevent such vibration I employ means to insure a frictional resistance to the movement of the arm 28 or other swinging carrier for the cop-spindle. It will be evident, however, that this resistance should be lessened as the winding continues and the package and its support swings upward. In the construction shown the stud 29 extends through the arm and through the arm 28, as best shown in Fig. 3, and a concave spring-washer 71 is pressed against the side of the arm 28 by meansof a cup-shaped nut 72, having threads adapted to coarse threads upon the stud 29. To insure the turning of the nut 72 with the arm 28, a clip 7 3 is bolted to the arm 28 and is adapted to engage teeth at the periphery of the toothed nut, which may thus be set to any desired position and then secured. As the arm 28 swings upward with the package the nut turning on the threaded end of the shaft 29 recedes from the end of the arm 28 and reduces the pressure and friction between the side of the said arm and the arm 70.

It is well known that variations in the resistance to the passage of the yarn from the supply result in consequence of the thread being drawn from the supply at an angle to the axis of the bobbin-supporting shaft or spindle. To obviate this objection, 1 so support the said shaft or spindle that it may be always set with its axis coincident with or substantially parallel to the line of draft. This may thus be done by supporting the spindle J upon the support K, whatever it may be, through the medium of a universal joint L. As shown, there is a bztll-and-socket connection, the ball at the end of the spindle litting a rounded socket in a clamp 76, which may be loosened by means of a screw-bolt 77 to set the spindle in position, and then tightened to hold it in place.

While any suitable tension device may be employed, I prefer to make use of that charactor of tension device in which there are two oppositely-arranged combs or sets of parallel alternating lingers or bars, one movable to and from the other, so as to impart a more or less tortuous course to the thread passing between them. The drawings illustrate an effective construction of this class of tension device, each comb consisting of a single wire 78, the ends of which are secured to a bar 79, while the intermediate portion is bent back and forth to form the parallel lingers or bars 80, as best shown in Figs. 1 and 5, and the curved ends and parts of the wire nearest the bar 79 are bent at an angle, as shown in Fig. 7, and the outer curved ends are bent to the same side, so that the central parts of the bars 80 are carried to one side of the bar 7.) and in position to meet the plane of the central parts of the bars of the other comb, the ends of which are bent in the reverse direction. This causes a divergence of the outer ends of the opposite combs, as shown in Fig. 7, so that the thread or yarn can be readilyinserted between them. Inasmuch as only the upper and lower bars of each comb have any direct support, the bodyof the comb will be more flexible and yielding and secure a better tension and effect than when the bars are each independently supported. The bar 79 is provided with a hub 81, through which extends the supporting-rod 82, extending from the frame and to which the bar is fixed, and the bar 88, supporting the opposite comb, is bolted toa frame or other movable support 84E, which slides upon the rod 82, and Where there are two or more tension devices all the bars 79 are secured to the rod 82 and all the bars 83 are secured to the frame 84, so that all the tension devices will have equal movement and adjustment simultaneously. The bars 83 and their combs are carried toward the opposite bars and combs by the action of the spring 85, which bears on a U-shaped frame 102, which supports the plate 20 and the pigtailguide 103, and the spring also bears on the frame 8 1 and shifts it to a position determined by that of nuts 86, adjustable upon the thread ed end of the rod 82.
